Best thing to do is let it dry for 5-7 days in an air conditioned room. Then see if it still works. No need to open it up.

why air conditioned room? – soul Jul 29 '10 at 3:14
lower humidity. – jer.salamon Jul 29 '10 at 3:16
Air conditioners partly work by sucking the water out of the air. This allows more water to evaporate out of the monitor into the air, through the air conditioner. – Austin Hyde Jul 29 '10 at 3:30

Depends on how much rain and what internal components got wet. Best bet let it dry and plug it in.

+1, but I'll add to let it dry thoroughly - much longer than you think it needs. – Joel Coehoorn Jul 29 '10 at 3:06

Definitely let it dry for at least a week. If possible, completely submerge it in rice (I know, that's a lot of rice), which will help dry it out. Make sure it looks completely dry from everything you can tell before you try to plug it in.

Rain is usually reasonably pure water and therefore nothing like as corrosive as carbonated drinks or fruit juices. If you don't want to be without your machine for a week you can accelerate evaporation significantly by leaving a desk fan on at the side of it. If you aren't worried about invalidating a warranty then you could consider getting some tools to open up the case. You might also consider using a hairdryer on low heat. If you do that, don't hold it too close or keep in in one spot long enough to heat anything up too much. Tke particular care to dry switches etc and anywhere where water might hide. Be sure that everything is really dry before you connect the power.

If you do spill liquids on PC components, disconnect them right away - don't stop to power the machine down. On a laptop, get the battery out fast. Open things up to access places where the spilled liquid might be lurking, but don't open any power supplies or high voltage components. Soak up any pools of liquid then use clean water to flush corrosive liquids away then dry thoroughly.

Open the screen and let the inside be exposed to open air for a while. Depending on the humidity of your place the water will evaporate slowly. Remember if anything strange happens disconnect the power fast as water with ions is a very good conductor of electricity and can cause a short circuit.

I don't think this really answers the question, the asker can not open the device do to lack of tools. – zeel Apr 14 '14 at 21:23
